Whatever!
A 7mm is a 7mm,and a 338 is a 338.
Point is well made by comparison. The Mashburn with these high BC bullets is an impressive, modern performer,and the performance comes with substantially less recoil than a 30 caliber or 338 with the same flight characteristics.And with bullets heavy enough to be reliable on most any open country animal.
That it "suits" in a 60 year old lightweight Mauser,or a specialized,modern LR rig demonstrates its adaptability.
